摘　　要：酒精废液是原料蔗制糖工艺末端重要的副产物之一,为更好地实现酒精废液资源化利用,本研究比较了添加不同改良剂处理的酒精废液对土壤养分和甘蔗产量及品质性状的影响。结果表明:(1)酒精废液连续施用能提高土壤有机质、有效磷、速效钾、交换性钙镁等养分含量,改良土壤酸性,但也增加了土壤氯离子含量;(2)酒精废液施用能增加甘蔗株高及产量,但会造成蔗糖分略有降低;(3)施用酒精废液75 t/hm^(2)+生石灰0.75 t/hm^(2)对土壤养分和甘蔗生长的效果最佳。研究结果表明施用改良剂处理的酒精废液有助于提升其对甘蔗生产的效果。Vinasse is one of the most important by-products at the end of sugarcane processing.To better realize the resource utilization of vinasse,this study compared the effects of vinasse treated with different amendments on soil nutrients and sugarcane yield and quality traits.The results showed that:(1)Continuous application of vinasse increased soil organic matter,available phosphorus,available potassium,exchangeable calcium and magnesium contents,improved soil pH,but also in creased the content of soil chloride ion(2)Vinasse application increased plant height and yield of sugarcane,but leaded to a slight decrease of sugar content;(3)Application of vinasse 75 t/hm2+quicklime 0.75 t/hm2 had the best effect on soil nutrients and sugarcane growth.The results indicate that application of vinasse treated with amendment could improve its effects on sugarcane production.
